A columned pool unlike any you have ever seen awaits you at the DIEDRICH Wellnesshotel & Spa. Two levels dotted with columns reminiscent of Roman baths and numerous loungers around the pool invite you to relax and unwind, while the swimming pool on the lower floor, with its 29°C warm water, entices you to take a mindful break. Another highlight is the view of the beautiful Sauerland countryside through the huge panoramic windows.

Here, you can enjoy relaxation with all your senses – and during a visit to our spa, you may even find yourself completely losing track of time. That's precisely why one of the relaxation areas at our spa hotel in North Rhine-Westphalia is aptly named "Zeitlos" (Timeless). Here, you can relax with all your senses while listening to the sound of birds chirping and enjoying pleasant lighting – whether in the hanging nests, on the comfortable double loungers, or on the soft upholstered furniture.
